The superconductivity of the conducting CuO 2 plane of the layered cuprates is considered in the framework of a two-dimensional (2D) tight-binding model which contains O2 p ฯ and Cu3d x 2 -y 2 states. Besides the standard LCAO amplitudes the correlated hopping between O2 p ฯ and Cu3d x 2 -y 2 orbita
